MACHINE FOR CUTTING AND TURNING WRISTBANDS.

SPECIFICATION forming part of Letters Patent N o. 632,308, datedSeptember 5, 1899.

Application led April 27, 1899. Serial No. 714,679. (No model.)

To @ZZ whom, it may concern:

Be it known that I, JOSEPH FIEscHINe, of Utica, in the county of Oneidaand State of New York, have invented certain new and useful Improvementsin Machines for Cutting and Turning Wristbands; and I do hereby declarethat the following is a full, clear, and exact description of theinvention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form part of this specification.

The object of my present invention is to provide a machine for cutting oand partially turning tubular knit fabrics, such as are used for cuffsand wristbands of undergarments.

In the drawings, Figure l shows a side elevation of the machine. Fig. 2shows the opposite side from that shown in Fig. 1. Fig. 3 shows a planwith the operative parts substantially at one of their limits ofmovement. Fig. 4 shows a similar plan with the operative partssubstantially at the other limit of their movement from that shown inFig. 3. Fig. 5 shows an enlarged section taken on lineA B of Fig. 3,together with the parts to the left of the section-line. Figs. 6, 7, and8 show details of grippers and gripper-operating mechanism employed inthe machine. Fig. 9 shows in perspective a fabric-expander employed inthe machine. Fig. 10 shows in perspective, removed from the machine, apair of feedrollers and their operating mechanism.

Referring to the lettersA and gures of reference in a more particulardescription, l indicates the frame of the machine, on which the workingparts are supported. Mounted inbearings in the upper part of the machineis the main shaft 2, which may be provided with the driving-pulley 3.The shaft 2 also carries a beveled gear-pinion 4, which meshes with asimilar pinion 5, mounted on a short longitudinal shaft 6, also ,carriedin suitable bearings on theframe. The shaft 6 carries the knife 7, whichwhile operating shears by the shearing-plate S, secured on the top ofthe frame. vThe fabric-expander 9 is arranged to take a position at theleft of the shearing-plate S, as the machine is shown in` Fig. 3, and issupported on a pair of bars or small rollers 10 and 11. The expander orextender 9 has a head portion 9a and divergent edges 9b, and there isarranged along the edges a series of small rollers m m to reduce thefriction of the tubular fabric. At the ends of the diverging edges 9bthere are provided -pairs of divergent spring-arms 9c 9c, adapted toextend or open up the end of the tubular fabric vertically. The expanderor extender 9 is adapted to take itsy position between the Verticalrollers 12 and 13 in the frame-thatis to say, the neck portion of theexpander is adapted to enter between these two vertical rollers. Theexpander is thus confined from movement to any material extent in eitherdirection. The rollers 12 and 13, which are mounted in suitable bearingsin the frame, are provided atthe lower end of the shaft on'which theyare mounted with gear-pinions 14 and 15, respectively, engaged by theright and left hand worms on the shaft 16. The shaft 16 is provided witha sprocket-wheel 17 and is drivenV from the shaft 2 by a sprocket-chain13.

For drawing and manipulating the fabric there is provided a pair ofgrippers A A. These grippers are mounted on the ends of a pair ofreciprocating arms 19 19. The arms 19 slide freely through eyes at 2O inthe frame and are secured in the sliding head 2l. The sliding head 2l is provided with projections 22, which run in grooves or ways on theinner side of the upper edge of the frame 1. For operating the grippersthere is provided a pair of cranks 22a 22a, mounted on opposite ends ofthe shaft 23, which shaft is mounted in suitable bearings in the upperside of the frame. The shaft 23 is driven from the shaft 2 by asprocket-chain 24, passing around the sprocket-wheels 25 and 26, securedon the shafts 2 and 23, respectively. The cranks 22n are connected withthe projecting ends of the head 21 by connecting-rods 27 27. By thisarrangement as the shaft23 is driven the cross-head 21 is moved backwardand forward in its ways on the frame, and with it the grippers A A arecarried backward `and forward, being carefully guided and directed bypassing through the eyes 20.

There are also provided in the machine a pair of supporting and turningfingers 28 28.

IOO

These fingers are secured in a sliding crosshead 29 and theholding-block 30. The crosshead 2S) is provided with projections whichengage in the grooves or Ways 31 on the inner side of the frame andslide freely therein. Secured in the cross-head 29 and the holdingblock30 is a rod 32, which extends to and freely slides through an eye at 33in the rear end of the frame. Rigidly secured on the rod 32 is an arm33, which projects downwardly and is connected at its lower end with aconnecting-rod 34. The connecting-rod 34 connects the arm 30 with acrank 35, formed in the shaft 36. The shaft 36 is driven by theintermeshing cog-pinions 37 and 33, secured on the shafts 36 and 23,respectively.

The grippers A consist of a fixed jaw 40 and a movable jaw 41, pivotedtogether at 42 and held in closed position by the spring 43. Foroperating the movable jaw 4l there is secured on the frame for each jawa pair of trippers 44 and 45. These trippers are blocks pivoted at theirmiddle in the supportingplate 46, so as to swing freely in onedirection, but being limited in their movement by pins 47 and 4S,respectively. W'hen not otherwise displaced or interfered with, thetripping-blocks 44 and 45 are held in their normal position crosswise ofthe plates 46 by the springs 49 and 50, respectively. It Will thus benoted that when the grippers A are moving in the direction indicated bythe arrow in Fig. '7 the shank portion of the movable jaw meets withpositive resistance from the trippers 44 and 45, and as the grippers areforced by the trippers the trippers operate over. the cam-face back ofthe movable jaw 41, so as to open the jaw, While, however, when thegrippers are moved in the opposite direction-that is to say, in thedirection indicated by the arrow in Fig. G-the end of the movable jaw 41strikes against the sides of the trippers, respectively, and they areswung on their pivots, as indicated by dotted lines in Fig. 6, and thejaw 41 is not operated, so that it will not lose hold of the fabric whenmoving in this direction.

The operation of the machine is substantially as follows: A tubularfabric of the proper size is supplied to the machine at the left-handend, as shown in Figs. 1 and 2, either from a reel or roll or otherwise.The -expander or extender 9 is removed from the machine and inserted inthe end of the tubular fabric, when the same is replaced in the machinein the position indicated in the drawings. The machine being in properpositionthat is to say, substantially that shown in Fig. 3-the end ofthe tubular fabric is carried slightly beyond the extender 9 and engagestime of this operation the rollers 12 and 13 are heilig driven andassist the fabric in passing the extender; also, at the time that thegrippers A are drawing the fabric over the expander the fingers 28 2Sare being moved toward the left from the position shown in Fig. 3 andpass within the tubular fabric, which is being brought forward bythegrippers A A. The arrangement of the parts is such that when thegrippers have completed their movement in one direction and the fingers28 their movement in the opposite direction and the parts aresubstantially in the position shown in Fig. 4 the swinging knife '7 hascompleted its revolution around with the shaft 6 from the cutting-plateS and now comesv into operation to sever the fabric at the edge of thecutting-plate 8. The continued operation of the machine then carries thegrippers A toward the left as the machine is shown in Figs. 4 and 3. Itmay be here noted that the outer sides of the fingers 2S are preferablyroughened similar to a file for rasp. As the grippers A move toward theleft, as shown in Fig. 4, the fabric is turned inside out on the fingers28, these fingers at the same time being retracted or carried toward theright. The arrangement of the parts is such that at the time that therear end of the jaw 4l comes in contact with the tripper 44 the turningoperation will be completed, and the grippers will then be released bythe operation of the tripper 44, releasing the edge of the fabric. Inthe continued operation of the machine the piece of partially or halfturned fabric is forced off from the end of vthe fingers 28 by thedependent hooks 52 52, carried by the cross-bar 53, extending betweenthe grippers A. At the same time the movable jaw of the gripper comesinto contact with the tripper 45 and is held open until the fixed jaw 40enters the open end of the tubular fabric held by the extender 9, whenthe jaw isv released and the gripper has again secu red hold of the endof the web of the fabric, and the continued operation of the machinerepeats the operation heretofore described. The partiallyturned piecesof fabric which are forced off IOO IIO

from the end of the fingers 2S fall into the i lower portion of themachine, Where they may be caught in a receptacle or basket placed forthat purpose.

All parts of the machine are preferably made adjustable, whereby themachine is adapted to various sizes of material, and the severalmovements of parts may be timed to a nicety. The cutting mechanism andother parts might be modified in many particulars without departing fromthe spirit of my invention.
